摘　　要：利用全量子理论,研究了耦合双原子与单模压缩真空场Raman相互作用系统场熵的演化特性,运用数值方法讨论了系统耦合常数对场熵演化特性的影响.The entropy evolution properties of field in the system of two coupling atoms with a single-mode squeezed vacuum field are studied by means of quantum theory.By using the numerical method, the relation between the entropy evolution properties of field and the coupling constant of two atoms and the coupling constant of atom-field is discussed.
